It looks like you may not have created any servers (servers hold data and locators help clients and other cluster members find servers). If not then you will need to start at least one server as well. Check the documentation but it would be something like this: "gfsh start server --name=server1 --dir=workdir --locators=localhost[40404] --server-port=1234"

Yes, and be sure to create the "People" region on the server that you create after following Randy's instructions to start a server. Also, a locator is launched on port 10334 by default (not 40404). A servers default port is 40404. You apparently got your locator and server confused. – Wes Williams Jul 02 '17 at 03:55

I using java config bean to connect locator, it still connect fail. But when i create CacheFactory using cache.xml. Example.

clientCacheFactory.set("cache-xml-file", "gemfire-clientCache.xml");

it can connect

<pool name="client"
        subscription-enabled="true">
    <locator host="172.16.175.145" port="10334"/>
</pool>
<region name="test" refid="PROXY"/>
<region name="test1" refid="PROXY">
</region>

but when i using clientCacheFactory.addLocators(),don't set cache.xml.it can't connect success
